That story is a nightmare tale, although a cracked rib is serious, I'm thankful it wasn't worse. The stock type systems work well, but hydraulic systems are a great solution if it fits in your budget. This incident should also prompt you to install and use a safety interlock, should you be tossed out. Good advice to all boaters, take some time to pre-flight your boats. Maybe the lost or loose bolt could have been noticed? Good locking hardware is a must on boats, especially those on the St Croix on Saturday afternoons😃
